PURPOSE:To reduce odor and prevent the air flow resistance from deteriorating and oxygen defficiency from occurring by constituting a wick lifting and lowering type kerosene burner so that air within an oil tank is sucked up by a wick lowering operation, and that air within an oil tank is sucked up by the operation of a thermal responsive switch provided on the outer wall of a wick outer cylinder. CONSTITUTION:A switch 25 is changed over to a normally open terminal 25a, a transistor 27 is turned ON, a motor 24 is actuated through the turning ON of transistors 28-31, and the fan 23 of suction means 18 sucks up air within a tank 11 and discharges the same. Kerosene vapor is sucked up into the tank 11 which is put into a negative pressure via a wick gap 14, and odor is reduced. Further, when oxygen becomes deficient or back fire occurs due to the air flow resistance to raise the temperature of a combustion cylinder and a thermal responsive switch 26 is turned ON, the motor 24 rotates reversely to reversely rotate the fan 23 to suck up air into an oil tank 11. Accordingly, the operation can be made strong to oxidation and air flow resistance. |
